Thanks for your response, Mr. Hayes.
Mr. Sean, please download and check if "timeout" is still present with built
RTL8153 module from REALTEK site, as Mr. Hayes proposed.
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=2&PNid=...
r8152.53-2.03.0.tar.bz2
Procedure - should be equal for both, Fedora 21 & 20:
$ uname -r
3.17.8-300.fc21.x86_64
$ su -c 'yum install kernel-devel'
$ tar xf r8152.53-2.03.0.tar.bz2
$ cd r8152-2.03.0/
$ make
$ su
# cp 50-usb-realtek-net.rules /etc/udev/rules.d/
# udevadm trigger --action=add
# modprobe -rv r8152
# cp r8152.ko /lib/modules/$(uname -r)/updates/
# depmod
# modprobe -v r8152
poma
OK. Did all that. Now to see if I get the same problem over the next
couple of weeks.
I'd never heard about the updates subfolder in modules. Very slick.
But when I update the kernel, I get to do this again correct? How will I
know that this module has been incorporated in the running kernel.
modinfo doesn't give any version info.
BTW, I'm not sure what modprobe --dump-modversions is supposed to do,
but it doesn't:
#modprobe --dump-modversions r8152
modprobe: FATAL: Module r8152 not found.
# modprobe --dump-modversions r8152.ko
modprobe: FATAL: Module r8152.ko not found.
#lsmod | grep 8152
r8152 49646 0
Thanks for all your help.
